It was never going to achieve an Avengers-style opening, but there are undoubtedly a few bigwigs out there who expected more from Paul Rudd's Ant-Man, which has opened to an estimated $58million in the US.

Paul Rudd ready to kick butt as Ant-Man

Marking Marvel's 12th consecutive first-place opening, Variety reports the superhero film opened comfortably in the top spot, ahead of Minions ($50.2m) in its second week.

Amy Schumer's well-received comedy Trainwreck debuted to $30.2m in third place. This was significantly higher than three other Judd Apatow-directed films - This Is 40, Funny People and The 40-Year-Old Virgin - behind only Knocked Up's $30.7m debut. And when the final numbers are in, Trainwreck may well turn out to be Apatow's biggest.

Some analysts expected Ant-Man to top $60m based on Friday takings, but its opening is, at least, in the region of The Incredible Hulk, which earned an initial $55m on its way to a $134million US haul.
